Sounds from space?

Recently I wrote in one of my posts that SETI had detected an unknown signal back in 2012. If you'd like to read more about it, here's the link: http://strangesounds.org/2014/03/is-this-the-new-alien-wow-signal-seti-has-recently-detected-a-new-unexplained-strange-sound.html. Now, I'd also like to tell you about ANOTHER unknown signal which has been detected. This time, though, it was detected by astronomers in Australia. For more info, here's the link to that discovery:
